Well, it is obviously a problem but I do not know what could have caused that! It happened when my car just got finished with the atr downpipe and exhaust(no cat) had gone on. I also had gotten a power plate. I wasnt sure where the boost was and when I pushed the car the first time, the crappy stock boost meter read about 10 psi and 8 degrees knock. Well, I knew that couldnt be good but just to see I floored it for a second later on, the boost went past the 15 psi limit and knock to 16.7! I immediately let off, good thing nothing was broken. I had not turned the boost down yet so I am guessing it was probably at 20 or so. But the thing is with 10 psi I had 8 knock? Anyway, I asked someone and they suggested a bad injector so I have gone through 2 tanks with injector cleaner but have not hooked it to the scanmaster yet, and I am running about 10 psi now just to be safe. Anybody see a problem? Also, maybe it could be my chip which I got about a year ago from bowling green customs. Either way I might get a thrasher chip to see if that might help
